"Says vote blue" is a very shallow description of the role he plays.
If you don't understand his role, I would encourage you to expand your analysis. Best way to do that is to listen in on a few streams instead of going off of clips and tweets.
If you can't figure out how to make him useful to your own propaganda, I think that's a skill issue. Hasan is an informer and educator doing the arduous task of re-education for you. As a better-educated socialist engaged in political practice in your community, you should be the political leader of those around you. Your voice should be louder than his to the people around you, but the good news is that if you post on Hexbear, you agree with Hasan 98.5% of the time.
